Samsung 840 PRO over provisioning ?
Posted 18 April 2013 - 03:25 AM
I recently brought a Samsung 840 Pro 512GB model, by default it's has a 9-10% not available for the user and it's used ( as far as I know ) for internal use of the controller ( garbage collection, etc ).
In some articles, forums, etc people is starting to leave unpartitioned space of the disk for over provisioning via the Magician Software of Samsung. I used all the space available by the drive ( 476GB ) so I don't know if maybe i need to repartition the disk just for leaving son space for over provisioning.
I used my computer primarly for Virtual Machines, for testing, training, etc so I don't know if this over provisioning could help or not. Normally the average free space on my disk is about 20% of the total.
Thanks in advance.

Over provisioning will make the garbage collection much more efficient and help keep your drive's write speeds from slowing over time.

Right now the disk has the 10% recomended assigned, it's by default so the disk has right now 476GB for use.
My question goes if it'a really useful to add more space with the overprovisioning, I mean, the current 10% + 10% more from unallocated space ??.

Repartitiong is only needed if you intend to fill your drive completely.

In this case It will necessary to add more op space ( apart from the default 10% ) ?.

I will the SSD as it is right now, with the defualt 10% as it seems is the best scenario.
